Documented reports were less certain to claim the benefits of it in an extended window period. EAST-AIS (CTRI\/2022\/03\/040718) trial is designed to determine the success rate of thrombolysis in an extended window period for good clinical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>It is a randomized, placebo-controlled trial of tenecteplase administered within 4.5\u201324 h of stroke onset (with or without large vessel occlusion) based on evidence of salvageable tissue through baseline computed tomography perfusion (CTP) or magnetic resonance imaging (MRI) scan. Criteria of patient inclusion are as follows: patients of both genders (male and female), age &gt;18 years, pre-stroke modified Ranking Scale (mRS) &lt;2, baseline NIHSS &gt;5, CTP showing penumbra\u2013ischemic core ratio &gt;1.8, absolute difference in volume &gt;10 ml, and ischemic core volume &lt;70 ml.
